How EV Batteries Work What Makes An EV Battery Function

Electric cars have come a long way in recent years. They’ve gone from being a niche market reserved for environmentalists and early adopters to becoming a mainstream option expected to take over the automotive market in the coming years. But what makes electric cars so special? The answer is the battery.

Without a good battery, electric cars wouldn’t work. So, for people who are planning to buy an EV, it’s important to understand how an EV battery functions and what makes it different from the battery in a gas-powered car.

In this article, we’ll look at how EV batteries work and what goes into making them function properly. This discussion will hopefully guide people and inform them on the importance of batteries when buying an electric car.


Types of Electric Car Batteries

There are four types of EV car batteries: Lead-acid, Nickel-metal-hydride, Lithium-ion, and Ultraceptors. Each of these batteries has its own set of advantages and disadvantages. However, they all serve the same purpose: to power the electric motor in an EV.

Electric Car Charging

Knowing how to charge an electric car is just as important as understanding how the battery works. After all, if you can’t charge your car, then you’re not going to get very far. 

Most electric cars can be charged using a standard 120-volt outlet, which will take anywhere from eight to 24 hours to charge the battery. For faster charging times, you’ll need a 240-volt outlet, which can charge the battery in as little as four to eight hours.

How Do Electric Car Batteries Work?

So, how exactly do electric car batteries work? Instead of the internal combustion engine found in a gasoline-powered car, an All-electric vehicle has an electric traction motor in which the battery plays a vital role. 

EVs use a traction battery pack, either of the four types of batteries. However, it is usually a lithium-ion battery. This battery stores the electricity used by the motor to move the vehicle’s wheels. 

The electric traction motor is powered by an alternating current (AC) produced by the onboard charger. The onboard charger is connected to the charging port, which is how the battery gets its juice. 

When you plug in your EV to charge, the onboard charger converts the AC from the charging port into DC (direct current), which is then used to charge the battery. The battery, in turn, powers the electric traction motor, which moves the vehicle’s wheels. It’s a simple process, but it’s essential to properly function an electric car. 

Keep in mind that there are different EVs, all of which work slightly differently. For example, a Plug-in Hybrid Electric Vehicle (PHEV) is powered by a traction battery pack. 

However, PHEVs also have a combustion engine—it runs on electric power until the battery is depleted, at which point the combustion engine kicks in. To learn more about the different types of electric cars, check out our article entitled, “How Do Electric Cars Work? Here’s All You Need to Know.”


The Lifecycle of an Electric Battery

How long will an electric car battery last? This question is often asked by those considering switching to an EV. After all, gas-powered cars can last for decades with proper maintenance. So how long will an electric car battery last before it needs to be replaced? 

The answer to this question depends on several factors, including the type of battery, how it’s used, and how well it’s maintained. For instance, the Tesla Roadster has a lithium-ion battery pack projected to have a lifespan of about 10 to 12 years—approximately 100,000 miles. At the end of that period, the battery pack will need to be replaced at an approximate cost of $10,000. Equivalent to saving $167 for the same period. 

It may seem expensive, but remember that a Tesla Roadster is one of the most expensive luxury EVs, priced at $100,000. If you purchase a standard $35,000 EV, the battery pack replacement cost would be less than that amount over the same period. Plus, it’s also projected that battery pack prices will decrease as EV becomes more mainstream.

In short, while electric car batteries will eventually need to be replaced, they should last for several years with proper care and maintenance. And as battery technology improves and prices decrease, EVs will become increasingly more affordable for the average consumer.
